SPECIFICATION forming part of Letters Patent No. 412,037, dated October1, 1889.

Application filed March 29, 1889.

To all whom, it may concern.-

Be it known that I, HosEA P. OSBOURNE, of Milwaukee, in the county ofMilwaukee, and in the State of 'Wisconsin, have invented certain new anduseful Improvements in Steam- Gcnerators; and I do hereby declare thatthe following is a full, clear, and exact description thereof.

My invention relates to steam-generators; and it consists in certainpeculiarities of construction and combination of parts, to behereinafter described with reference to the accompanying drawings andsubsequently claimed.

In the drawings,Figure 1 represents a portion of my device partly inelevation and partly in vertical longitudinal section; Fig. 2, avertical transverse section on line 2 2 of Fig. 1; Fig. 3, a transversesection of aspr ay pipe that constitutes part of my device, and Fig. 4 adetail sectional view of a portion of the bottom of thegenerating-chamber.

Referring by letter tothe drawings, A represents a furnace, and B agenerating-chamber supported above the furnace. The generating-chamber Bis provided with a lining 0 around three of its sides, and this liningand adjacent walls of said chamber form a water-space D, connected by apipe E with a reservoir F, as illustrated in Fig. 1, and a pipe Gconnects said generating chamber and reservoir.

Connected with the water-space D are perforated longitudinal pipes H,that discharge into the generating-chamber B, the bottom I of thisgenerating-chamber being preferably corrugated, for the purpose to behereinafter described.

A steam-pipe J leads from the generatingchamber B, and a valvedwaste-pipe K is also connected to said generating chamber, the latterbeing preferably provided with a steamgage L and safety-valve M, asshown in Fig. 1.

In the operation of my invention a valve N in the pipe E is opened andthe water from the reservoir F flows into the water-space D and spraysout through the perforated pipes H into the generating-chamber B, to beconverted into steam, this conversion being very rapid owing to theintense heat within said generatingchamber. By having the bottom of thegenerating chamber corrugated a SerialNo.305,237. (Nomodeh) greaterheating-surface is presented to any of the water that may find its waythereto, and the corrugations are such that narrow spaces are left forthe water and materially wider spaces presented to the fire, whereby theconversion of said water into steam is more rapidly effected. It willalso be observed that the water-space is materially less in area thanthe generating-chamber, and consequently the water is rapidly heatedbefore it sprays into said chamber, thereby facilitating the operationof converting said water into steam. The steam finds its way out throughthe pipe J to the point of utilization, and also through the pipe G toincrease the pressure within the reservoir, and thereby equalize thesteam-pressure on the water that flows through the feed-pipe E.

Should any water accumulate in the generating chamber it will find itsway out through the valved pipe K shown in Fig.1.

By the construction above described I provide a very simple device forthe purpose of generating steam, and steam thus generated is very dry,because a comparatively small volume of'water is first heated and thendistributed into a heatingchamber in the form of spray, where it israpidly converted into steam, and such water as may not be thusconverted falls into the narrow spaces of the corrugated bottom of saidchamber in opposition to such an area of heating-surface that steam isthe immediate result.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. A steam-generatorcomprisingafurnace, a generating-chamber supportedabove the furnace and provided with aWater-space, perforated pipesconnected to the water-space and arranged in the generating-chamber, areservoir also connected to said water-space, and a steam-delivery pipeconnected to the generating chamber, substantially as set forth.

2. A steam-generator comprising a furnace, a generating-chambersupported above the furnace and provided with a waterspace andcorrugated bottom, perforated pipes connected to the water-space andarranged in the geucrating ohamber, a feed-water supply also connectedto said water-space, and a steam-delivery pipe connected to thegenerating-chamber, substantially as set forth.

3. A steam-generator comprising afurnace, a generating-chamber supportedabove the furnace and provided with a Water-space of limited area, afeed-Water supply connected with the water-space, distributor-pipes alsoconnected With said Water-space and arranged Within thegenerating-chamber, a corrugated bottom for said generatingchamberconstructed to present narrow Water-spaces and materially widerfire-spaces, and a steam-delivery pipe, substantially as set forth.

4. A steam-generator comprising a furnace, a generating-chambersupported above the furnace and provided with a Water-space, perforatedpipes connected to the water-space and arranged in thegenerating-chamber, a feed-water supply also connected to the saidWater-space, a steam-delivery pipe, and a valved Waste-pipe connected tothe generating-chamber, substantially as set forth.
